  Harvesting operations in Turkey are performed using traditional methods employing mostly animals and manpower for skidding and tractors mainly for winching. To apply these methods efficiently, the trees have to be bucked into short lengths logs (3-4 m), which reduces log values and overall profits. To produce longer logs, aerial harvesting methods such as cable logging and helicopter logging could be implemented, especially in productive forests located in steep mountainous regions of Turkey. Almost all of the forests in Turkey are state forests and managed by the General Directorate of Forestry (GDF). The GDF uses helicopters in firefighting activities; however, helicopters have not been used in harvesting operations. Using helicopters in both firefighting and harvesting may increase the utilization rate of helicopters and reduce the average helicopter unit cost. The purpose of this study is to identify the factors affecting the cost and productivity of helicopter logging and to analyze the utilization of helicopter logging in Turkish forestry.
